This is such a great forum!!

Well my clutch is about gone, and the way my luck is going I got only a week or two if I'm easy on it. I would like some idea where I am currently at on HP/Torque and what HP/Torque I should expect with twins. I would like some ideas on which clutch to get with the mods that I have and are planning. I Tow (12000 lbs) and Drag Race a few times (when the Race Car Breaks) but I don't think that I will ever pull. but who knows?

Thanks A Bunch!!

sounds like you oughtta go with a SBC DD. 3600 at least, maybe the 3850.

I think a South Bend ConFE would be fine if you never plan on pulling, but a dual disc is the only way to go if you are going to pull much. They are just slow shifting, and not ideal for pulling a trailer in my opinion because it takes you a while to shift, where a single disc is smooth, and quick.

South Bend DD 3850 12CB all the way. Good tower and she'll handle all the power you can throw without breaking your leg changing gears.

See thats what everybody told me before I got my DD. This thing drives as good as the stocker, heck, I like the feel of it better than the factory clutch! It shifts just as fast, at times its a bit harder to get in gear. But dang I love it. And its super quiet. Im running the SBC 3600 12cb.

I ran a South Bend Clutch on my 96'. Loved it. I think it was called the Rally Clutch. Call Peter and see what he recommends.

Like you, I plan on racing the truck, and don't want to rule out towing in the future. When I talked to Peter, he reccomended the 3600 lb 6 CB clutch. Thats what I ended up getting. Its a bit slower than stock (especially on the 2-3 shift), but I'm happy with it thus far. And I've read that it loosens up a bit once you get some miles on it. If not, I guess I'll just have to do the launches from 3rd.

so what hp and Torque am I pushing do you guys think? I will be getting a SBC. in a week why mess with the rest when SBC is the best!! Thanks again!!

I would suggest Haisley's Street drag twin. I have had it in my for two years and never a problem. Great street twin in my oppinion.

with the mods listed in your signature you are way over fueled on that 35/40 hybrid but you are prolly around 430hp. a bigger turbo will get you up to about 480ish.

how bad are your egts with the comp turned up? i know you can peg them but its a matter of how fast does it get to 1500?

idracingcop

thanks for the replys, I haven't turned up the comp past 2x4 if I drive the truck easy the clutch works ok no slip, but if I lay into it to pass or pull a hill with a trailer it slips and I have to back out of the throttle. I can get to 1250 pretty fast but when I tow I back the comp off and drive by the EGT gauge. I've gotten some good prices on clutch, and should have the $$ in about two weeks. I hope that over the winter I can get funds saved up for twins/O- ringed/studs that should help the EGT issue, and clean up alot of the smoke that I am making.

If your wanting twins you should go ahead and get the DD 3850.
IMHO

I got a great price from some really great guys (Local Diesel Performance shop) on a SBC DD 3850 installed for $1700 or $1600 if I do the install. They have helped me out of a few binds and have never steered me wrong on what parts I need.

Ph4tty

Why?? The 3600 is rated at 650 hp for the 6 or 12 button. 3850+ is for pullers.

idracingcop

The cost is the same so if I go with the bigger one I'll be ready if I really start kicking it up in HP/Torque. I always seem to push thing untill they break then fix that weak link and push it some more. I got the HP bug!!
